AI Technical Summary
Technical Problem
RoCE networks suffer from cluster network congestion, which affects network performance.
Method used
The network controller determines the available paths between the sending and receiving devices and calculates the entropy value. The sending device allocates paths based on the entropy balance principle, and the receiving device feeds back path quality information to adjust the credit value and entropy value set, thereby achieving load balancing and path optimization.
Benefits of technology
It effectively reduces network congestion and packet loss, improving network performance and transmission efficiency.

Abstract
The application provides a data transmission system and method. In the application, a network controller in a RoCE network perceives a communication relationship in advance and arranges paths between a sender device and a receiver device to obtain an entropy value of available paths between the sender device and the receiver device. Then, the network controller links with the sender device to send the available paths and the entropy value between the sender device and the receiver device to the sender device, so that the sender device allocates the entropy value to a message to be sent according to an equalization principle. The equalization principle ensures that communication between the sender device and the receiver device can cover all available paths between the sender device and the receiver device, optimizes the use of the network, realizes load balancing of all available paths between the sender device and the receiver device, avoids transmission of a large number of similar messages through the same path, effectively reduces problems such as network congestion and packet loss, and improves network performance.
